navigation controls are extremely dodgy. I'd love to leave them in, but when you click forward or back, you're 'fighting' the internal timer.. example:

You Click Back ... Transition begins.. takes time to do it's 3-D thing.. .. but by the time the transition is done and the picture is up, the 4-second timer has already reset and therefor the picture gets thrown to the next image before you even get a good look at the picture you navigated to.

I'd like to see the navigation buttons add at least a few, if not several, seconds to the timer to prevent this so people have a chance to not only see the photo they've navigated to, but perhaps navigate to another one as well, rather than be tossed around by the timer.
